5  Maintenance 

 
 

5.1  Batteries 

 

 
Battery condition is always displayed. See the battery condition indicator in the left 
side of the display. Observe the battery condition even during measurements. Results 
obtained with low battery voltage (the results may be incorrect) will be marked with 
“

bat

” mark after finishing the measurement.  

 

Replace all four batteries when they are empty in static mode (no measurement 
is running) or when the battery indicator shows an empty frame just 
temporarily, while a measurement is running! 
 

Nominal power supply voltage is 6 VDC. Use four 1.5V alkaline batteries type IEC 
LR14 (dimensions: diameter = 26mm, height = 50mm). 

 

 

Fig. 27:

 Correct polarity of inserted batteries 

 

One set of full-capacity batteries can supply the instrument for approx. 50 
hours at the ratio measurement / pause = 5 s / 25 s. 

 

- 

Disconnect test cable and switch off the instrument, before 

removing battery compartment cover! 

 

- 

Hazardous voltage under the battery compartment cover!
